Abstract (en)
[origin: EP4105250A1] The present invention provides a resin composition for stereolithography that excels in strength, toughness, and water resistance in the form of a shaped article. The present invention relates to a resin composition for stereolithography that comprises a urethanized (meth)acrylic compound (A), a (meth)acrylate compound (B) containing no urethane bond, and a photopolymerization initiator (C),the compound (A) being a urethanized (meth)acrylic compound (A-1) having a polymer structure, and/or a urethanized (meth)acrylic compound (A-2) having no polymer structure,the compound (A-1) having a weight-average molecular weight of less than 1,000,the compound (A-2) having a molecular weight of less than 1,000,the compound (B) comprising at least one selected from the group consisting of a (meth)acrylate compound (b-I) represented by general formula (I), and a (meth)acrylate compound (b-II) represented by general formula (II). Descriptions of the symbols in the formulae are omitted.
